WIPO Patent Application WO/2018/072467

A1

A ball valve applicable to vehicle gas fuel dispensing is provided, comprising a valve body (1), a valve seat (2), and a valve ball (3). The valve seat and the valve ball are located inside the valve body. A surface of the valve ball is provided with two circular through holes (4), and channels formed by the two circular through holes are perpendicular to each other. A flow guide cavity (5) is further disposed inside the valve ball. The flow guide cavity is in the shape of a polyline with only one vertice. The valve ball is located in the center of the valve body and connected to the valve seat (2) located at two sides of the ball. A valve seat support (6) is further disposed in the valve body. The valve seat support is connected to the valve seat. A disc spring (8) is further disposed between the valve seat support and joints located on two sides of the valve body. The present invention can solve problems of gas leakage and a ball valve having a short service life and needing to be frequently replaced caused by difficult gas fuel dispensing when using a common ball valve and excessive pressure required for gas fuel dispensing.
